kApplication led September 18, 1919. Serial No. 324,585.

To all whom it may concern:

le it linown that I, EDGARE SPENCER LAoH- MANN, a citizen of the United States, residp ing in the city of Chicago, county of Cook,

y specification, reference being had tothe Htl accompanying drawings, forming a part thereof. l n

rlhe purpose of this invention 1s to provide an iuiproved metal fencel post adapted to be self-anchoring in the ground, and to be held more'securely by itsanchoring than like postsy heretofore in use. VIt consists in the elements and features of construction shown and described as indicated in the claim.

lin the drawings;

Figure l is a persp'ectiye view of the fence post having an anchoring lhase emhodying this invention. 4 y hig. 2 is a direct or forward side elevation of the lower portion of the post comprising the anchoring elements.

Fig. '3 is a view similarto Fig. 2 showing the same invention applied to or embodied in a post of which the main element is a channel bar. y

lfig. 4 is a similar view, partly sectional, showing the invention embodied in an I- beam post.

Fig. 5 is asimilar view showing the invention applied to an angle bar post.

.The post proper consists of the metal bar, l, of? any flangular or angular cross-section,

having the several webs or flanges or certain of their beveled to sharpen the lower end of the post, for facilitating ydriving it into the earth.

The, anchor device comprises two flat bars, 2-2, riveted to the stem flange of the T-bar as seen atv3 in Figs. 1 and 2 or to the outer sides of the side flanges of the channel bar` post as seen in Fig. 3, or to opposite sides of one flange of an angle bar post as seen in Fig. 5, or to the opposite sides of the web of an Lhearn ost as seen in Fig. 4'. In any of the forms hoth said bars, 2 2, are bent outward so as to diverge upwardly from the flange or flanges or web to which they are secured, and from each other, at a wide angle, so that they are at an angle to each other from 40 to 60 and thereby at their upper ends are spread from said web,iange or flanges of the post to which they are secured, from one-third to one-half their length measuring from the point at which they diverge from said web, flange or flanges. These bars, 2-2, are connected together and secured to the main post member by cross tie-bar, l, which is riveted to Y the cross flange of the T-bar, or to the web of the channel baror to the other flange of the angle bar, or to the opposite flange of the .I-beam (as shown in the several figures showing these several forms of main post members), and are bent obliquely to the width of -the bar at the ends to lap on to and be secured lto the portions of the bars, 2-2, to which the cross bar is riveted as seen at 6.

The purpose and operation in practice of this construction is, that when the post is driven into the ground, the earth forced aside by the diverging `ba1s,2-2, readily returns to the inner side of those bars on both sides, rentering from the one side freely 'heu tween said bars and the stern flange of the T, and from the other side through the triangular openings, -f-fl, which, by reason ofl the proportions of the several parts, are relatively large and permit free entrance ofY the earth through said openings, as well as above the cross bar.. The earth-wound, as it may be called, produced by the driving in of the post, is thus self-healing by the normal falling in of the earth through the gap originallyV rodnced bythe diverging bars 2.-2, and t e earth `quickly becomes loade between and upon these bars, causin them to effect a very secure anchorage oft e post in the earth. The' breadth of the diverging anchor bars, 2-2, as well as the loading of these bars by the earth which enters between them, tends strongly to oppose dellection of the post in the direction of the length of the fence; and the breadth of the cross bar added t'o the breadth of the cross flange of the T-bar and the corresponding flange or web in the other forms, strongly resists deilection of the post laterally with fence. i

I claim: y

An anchored metal fence post of which the'main post member consists of a inetal bar having a plurality of longitudinally extending flanges angularly disposed with re spect to each other; anchoring elements con sisting of bars secured to oppcsite surfaces respect tothe of certain of said flanges and bent divergently upwardvandoutward at a Wide angle, and a cross-te-bar connecting the upper and Wide spread ends of said anchor ele- -ments secured to another flange or web of large triangular apertures between the post member and the tie-bar.

In testimony whereof, I have hereunto l0 set my hand at St. Paul, Minnesota, this 13 day of September. 1919.
